Moving a 200-ton reactor vessel across a refinery yard, or a 500-ton bridge segment onto its piers, is not a job for a standard truck or trailer. It calls for an equipment that can spread enormous concentrated weight across dozens of wheels, steer with millimeter precision in tight spaces, and keep the cargo level even when the ground underneath it isn’t.
Available across a 50 to 1,000 ton capacity range, the Haitai hydraulic platform transporter is a heavy-duty multi-axle trailer solution for oversize and overweight cargo handling. Whether transporting a prefabricated building module across a jobsite, loading a transformer onto a barge, or shifting a ship segment within a dry dock, the Haitai transporter is designed to allow cargo—typically requiring cranes, gantries, or custom rigging—to simply roll into position.
Haitai hydraulic platform transporter is commonly known in the industry as Hydraulic Platform Transporter (HPT). It covers capacities from 50 to 1,000 tons and features a modular multi-axle design, depending on its setup. Every axle line is equipped with its own hydraulic suspension, independent steering, and load-sensing mechanism, and multiple axle lines can be linked to create a unified, continuous deck.
Engineered as a modular, hydraulically towed multi-axle heavy-haul system, the Haitai Hydraulic Platform Transporter is built to transport loads between 50 and 1,000 tons across industrial facilities, ports, shipyards, and construction sites. Its foundation lies in independently steerable axle lines with hydraulic suspension, which evenly spreads concentrated loads over the ground—enabling it to carry cargo beyond the safe handling limits of standard trailers or cranes.
Thanks to its modular structure, axle lines can be connected side-by-side or end-to-end, adjusting both capacity and footprint precisely to suit the load—be it a wind turbine nacelle, a pressure vessel, a precast bridge girder, or an entire ship block. This adaptability defines the transporter: a project requiring 80 tons today may demand 400 tons next year, yet the same axle-line components can usually be reconfigured or expanded instead of necessitating a completely new unit.
HT crane hydraulic platform transporter models’ each unit is factory-assembled, fully load-tested, and CE certifiedready for shipment. They centers on three core objectives critical to heavy-haul operators:
A Haitai hydraulic platform transporter is built from a set of standardized modules that combine to form the complete transport system:
A high-strength, precision-welded steel frame, typically box-section or I-beam construction, that forms the load-bearing platform. This frame is engineered to resist bending and torsional stress under concentrated heavy loads while keeping overall deck weight as low as possible.
The modular “building blocks” of the system. Each axle line contains its own wheels, tires, hydraulic suspension cylinders, and steering mechanism, and can operate independently or in synchronized groups.
A network of hydraulic cylinders connected to each axle that automatically equalizes pressure across all wheels. This keeps the load level and evenly supported even when individual axles pass over uneven or sloped ground.
Rack-and-pinion or hydraulic cylinder-actuated steering at each axle line, allowing straight-line travel, crab-walking (pure lateral movement), diagonal movement, and pivot-turning within a small footprint.
The onboard or towed diesel (or electric) engine and hydraulic pump system that supplies power for propulsion, steering, and suspension leveling.
Standardized lateral and longitudinal coupling points that let individual modules bolt together to form wider or longer platforms, scaling capacity to match the cargo.
A centralized, often wireless remote control panel that lets a single operator coordinate steering, leveling, and speed across every axle line simultaneously, ensuring synchronized movement across the whole platform.
Independent hydraulic or pneumatic braking on each axle line for controlled deceleration and safe holding on grades.
Integrated lighting, warning signals, and pressure-monitoring sensors that alert operators to any imbalance in axle loading during transport.
The Haitai hydraulic platform transporter works by converting a single massive, concentrated load into many small, evenly distributed loads spread across dozens of wheels — which is what makes it possible to move cargo that would otherwise crush a normal trailer axle or exceed a crane’s capacity.
The Haitai hydraulic platform transporter is used wherever cargo is too heavy, too large, or too sensitive for conventional transport equipment:
Specifications vary by configuration (number of axle lines, deck width, and drive type), but the table below outlines the typical parameter range across the Haitai 50-1000 ton series.

If you handle heavy containers, steel structures, or oversized industrial cargo — and your site lacks fixed power infrastructure — a hydraulic straddle carrier is likely the most practical solution available. It lifts, travels, and places loads without needing overhead structures, rails, or high-voltage power supply. One machine. Full mobility. Minimal civil works. What Is a Hydraulic Straddle Carrier? The Core Concept A hydraulic straddle carrier is a self-propelled heavy lift vehicle. It straddles a load — lifting from below using a hydraulic spreader or lifting beam — and moves freely across the yard on rubber tyres. The entire lift-and-travel cycle is powered by an onboard diesel-hydraulic system. Unlike electric or cable-reel powered cranes, the hydraulic straddle carrier carries its own power source. This makes it fully independent of yard infrastructure. You can deploy it anywhere your surface can support the wheel loads — no fixed installation required. How the Hydraulic System Works The engine drives hydraulic pumps that supply pressurized fluid to the lift cylinders, drive motors, and steering actuators. All motion — lifting, lowering, travelling, and steering —…
Looking for a heavy lifting system that handles loads other cranes simply cannot? Our hydraulic gantry crane delivers lifting capacity from 10 to 1,000 tons, millimeter-level synchronization precision, and a modular structure that assembles quickly on any job site — indoors or out. Trusted across power generation, shipbuilding, metallurgy, and civil engineering, this is the heavy lifting equipment built for projects where performance cannot be compromised. What Is a Hydraulic Gantry Crane? A hydraulic gantry crane is a heavy-duty lifting system powered entirely by a hydraulic drive system. It consists of six core components: a gantry frame, lifting mechanism, traveling mechanism, hydraulic power unit, electrical control system, and safety protection devices. The system raises, positions, and moves extremely heavy loads with stepless speed control and ±1mm synchronization accuracy across multiple lifting points. It operates on standard AC 380V / 50Hz power supply or a self-contained diesel power unit — making it deployable anywhere, with or without grid power. Core Technical Specifications Parameter Specification Lifting Capacity 10 – 1,000 tons Span 8 – 35 m Lifting Height 4.5 – 12 m…
If you manage a marina, boatyard, or naval facility, you know the frustrations: vessels waiting endlessly for maintenance, docks that aren’t designed for heavy loads, and cranes that aren’t suited for waterborne operations. A Floating Dock Crane solves all these problems in one versatile machine. It lifts, moves, and positions vessels safely — without permanent dock modifications, without hull damage, and without slowing down your workflow. This page covers everything you need to evaluate a Floating Dock Crane: how it operates, where it performs best, what sets ours apart, and the complete technical specifications.
